Black Oxide
Black Oxide Coating is a process which provides a conversion coating on iron which changes the surface of the material to a naturally occurring black iron oxide.
Description
Dacromet / Geomet process can be used for protection of various items like fasteners, springs, break disc etc. The process involves two coats / two bake to get the desired results. Coefficient of friction for fasteners can be modifical using additional coat of top coat. The application of top coat also improves protection against corrosion. Both Dacromet & Geomet Processes comprise of uniform deposition of overlapping Zinc, Aluminium Flakes on inorganic binder, Dacromet process contains hexavalent Chrome whereas. Geomet process is totally chrome free.
